Genericity of responses and adaptation strategies to multiple stresses in organisms of aquatic and terrestrial ecosystem

>>> Download PDF document (lecture and poster abstracts) This workshop was organized by the Axe fédérateur Ecologie des stress abiotiques et contaminants, Ecotoxicologie (ECOBIO laboratory) Organizers : Cécile Sulmon-Maisonneuve (ECOBIO) and Claudia Wiegand (University of Southern Denmark - Chaire internationale UEB "agronomie, l’environnement et le développement durable" - ECOBIO) In anthropogenic-impacted environments, organisms face exposure to multiple stresses from various anthropogenic sources (i.e. pesticides) in addition to natural abiotic (i.e. extreme heat/drought) or biological stressors (i.e. parasitism/viruses). This workshop aims to present research pursuing environmental realistic scenarios, covering responses to stresses from the species level via their interactions in communities and consequences on ecosystems dynamics and functioning. At the individual level, comparison of species responses to multiple stressors, together with species long term reactions (multigenerational acclimatization or adaptations) will elucidate capacity / plasticity but also genericity of stress responses. Stress responses may be understood as molecular-physiological reactions as well as life trait reactions. We welcome expertise of both, ecologists and ecotoxicologists to contribute to an effective discussion evaluating how ecosystem functioning may be impaired. The round table will also use the opportunity to plan and discuss on an application at either French or EU level project funding.
